oaZZ whom t may concern.: Y

Beit known that I, EMIL RDRAVER, a citizen of the United States, residing at Alliance, in the county of Boxbntte and State of Nebraska, have invented a new and useful Improvement in Conveyers,of which the following is a Specification.Y

The object of my improvement is to pro#y vide a construction of apparatus for conveying material, particularly of a character which is readily penetrable by aI shovel, such as iiour, meal, grain, dac., whereby the particles of the material shall be conveyed with the least attrition, in a clean and expeditious manner and with the least'expenditure of power.

A further object of my improvement is to render the conveying means reversible, thereby to permit the material, or a portion of it,

to be conveyed in different directions at the will of the operator. A peculiar advantage of my improvementv in this particular, especially when the conveyer is used in connection with bolting-reels, purifiers and other flour-mill machinery consists in its being reversible while the machine is in operation,

In its broadest sense my invention consists in a support forrth'e material to be conveyed, a series of shovel-gates pivotally supported to engage the material toward their lower free ends, and reversible against stops located in vertical line directly beneath /the vshovel-gate pivots and means for imparting reciprocating motion to the said support or to the shovelgates, or both, that is, to the one with relation to the other whereby the material may-treadily pass under the shovel-gates in the direction in which they rise, but will be advanced by them in the opposite direction.

My invention also consists in details of construction and combination of parts, as hereinafter set forthand pointed out in the claims.

Referring to the accompanying drawings, Figure l shows my improved conveyer by a View in longitudinal sectional elevation. Fig. 2 is a similar view. of the same, showing a modification. Fig. 3 is a View of the machine in end elevation. Fig. 4: is a section taken at the line 4 on Fig. l and viewed in the direction of the arrow. Fig. 5 is a section taken at the line 5 on Fig. 2 and viewed in-tlie direction of the arrow. Fig. Gis a section taken at the line 6 on Fig. 2 and viewed in the direction of the arrow.

Al denotes a supporting-framefor the apparatus, and is shown as. comprising end posts fr, r and fr', r in pairs, 4suitably braced at their bases and from a' member of each pair to the corresponding member of the opposite pair, the members of the respective pairs being connected at their upper ends by the cross-rails r2 and r3. f

B B are two parallel side bars connected together toward their opposite ends, by crossbars q andA q', as shown in Fig. 1, or otherwise. At their lower ends the side-bars B rest on a base C. As represented in Fig. 1, the base C forms a stationary bottom of a rectangular oblong boX D rigidly supported between the posts r, fr and having the end discharge-openings o and n, provided, re-

spectively, withthe hinged valves 0 and 'f7/,'-

with, or at least almost reach at their lower ends to,'th'e upper surface of the base C. I form these shovel-gates ot' adequately stili? material, preferably vof sheet metal; and below the'pivotal point of each shovel-gate to extend beyond opposite sides of an imaginary vertical line depending from each pivot I provide a stop p having the oblique ends, as shown, to afford bearings for the shovel-gates, which, as indicated in Fig. l may readily be turned to occupy the positions represented by full lines or those represented by dotted lines.

For imparting movement to the apparatus, I provide an eccentric F on the drive-shaft t' carrying the belt-wheel t" to work in a frame F connected with a movable portion of the machine. Thus, according to Fig. 1, the frame IOO F is connected with the side-bars B at the cross-piece q; and according to Fig. 2, the frame F is rigidly fastened to the base C of the movable box D.

The operation is as follows: With the material to be conveyed on the base C and the shaft i set in motion, theaction of theeocentric F with the connection shown in Fig. l is to reciprocate the side-bars B, and, with the connection shown in Fig. 2 to reciprocate the base C. The one action has the effect of sliding the shovel-gates over the material when the side-bars B are moved in the direction in which the shovel-gates may be raised in their full line position; and movement Aof the side-bars in the opposite direction engages the shovel-gates, owing to the stops p behind` them, with the inateriaLcausing them to dig into thelatter, and, .by the advance of the side-bars, conveying the material toward the opening o, through which it discharges. The

other action, (according to the construction representedin Fig. 2) has the effect of sliding the movable `base C Withthey material upon it underthevshovelfgates when the sidey bars B are moved in thedi'rection in which the shovel-gates may be raised; and movement of the base in the oppositedirection engages the materialupon it with thefshovelgates, thuscausingit to be conveyedtoward sition of theshovel-gatesfmay readily be reversed by turning them on their hinges.. to extend as shown :by the dotted-line representation. It is intended that one half of the series of shovel-gates `shall extend, thus, in one direction, and the other half in the other direction, whereby the reciprocating action of the movable part of the machine shall, in the one operation, convey the material,v to and discharge it at both ends ofthe apparatus. Moreover, it will be obvious that reversal lof the shovel-gates may be accomplished while the machine is in operation, which is a very desirable feature when the conveyer is used in connection with fiour-millmachinery. l show no special means for facilitatingthe operation of turningthe shovel-gates; but such means may be readily provided, if desired, by those skilled in the art, without departing from my invention. The construction herein shown and described may, also, be modified in various ways without departure from my invention. Hence I do not wish to be understood as limiting the same to the details of construction set forth. It would also be within my invention to provide for reciprocating both the shovel-gate support and the material-support simultaneously in opposite directions.

My improvement is to be carefully distinguished in the art from a conveying apparatus known to me, wherein sifting surfaces are supported in a gyratory frame carrying, to move with thesiftingsurfaces, hinged cautboards.

According to my improvement, as hereinbefore explained, the function of the hinged shovel-gates results from their stationary relation to the moving surface carrying the material, or to the surface being stationary while theshovel gates move.

WVhat I claim as new, `and desire to secure by Letters Patent, is-

l. In a conveyer, the combination of a supu port for the material to be conveyed, a series of shovel-gates pivotallyand Lreversiblysupported to engagedsaid material at their lower free ends, stops forthe shovel-gates located in vertical linedirectly beneath their pivots and y against which said gates are reversible, and

`driving means for reciprocating, one with re.

lation Vto the other, said support" for the ma.

terial and thcshovel-.gate support, substan v tially as described.

2. In a conveyer, the combination of abase forming a support for the material to be conveyed, side-barsabove said base, shovel-gates pivotally and reversibly supported, between said bars at suitable intervals apart to engage, at their lower, free ends thel material, stops for thesliovelgateslocatedon said side-bars in vertical line directly beneaththe pivots and against whiclrsaid gates are reversible, Isaid support and the sidebars being relatively reciprocable, and driving means for imparting the reciprocating motionfsubstan'tially as described.

3. In -a conveyer the `combination with a supporting-frame A of a box D, side-bars B in said box, shovelgates E pivotally and re-v versibly supported between said bars, stops p on the side-bars in vertical line directly beneath the shovel-gate pivots and against which said gates are reversible, said base and the side-bars being. relativelyVv reciprocable,` and 4said eccentric is confined, substantially as described.
